The Rinstrum 2100EX is a NSC Trade Approved (using the listed power supplies) hazardous environment indicator. An EX version of the 2101 remote display is also available and connects via the serial port.

• Specialised weighing functions: lb/kg Switching, Live-Weight, Hold & Peak Hold, Totalising and Counting. The unit is versatile with 3 isolated (open collector) input/outputs provided standard. These can be used as setpoints or external keys.
•  Built-in applications: Basic check (catch) weighing (low/correct/high) and batching functionality for 1 material with single or dual speeds and dump are provided standard.
• Flexibile power options: The unit is available in three powering options, DC, AC and battery (using EX approved power supplies).
• Serial Output onboard: The RS-232 serial output is provided standard for use with a remote display, printer or connection back to a PC.
• Mulitple housing options: The instrument is available standard as panel mount or optionally with a stainless steel housing if a desk mounted solution is required.
